The arbitrary control of electromagnetic (EM) waves is a key aim of photonic research.Conventional optical materials have limited abilities to manipulate EM
We report some of our recent developments on flat plates or metasurfaces to structure the visible light in an altemative fashion.In this context,the followi
With the help of plasmonic resonance in metallic nanostructures,light absorption at visible and near infrared regime can be significantly enhanced.Such stro
